Hey !fediverse - there was an (Australian?) !XMPP web front-end that made extensive use of pubsub a couple of years ago. Anyone remember what it was? (I already got a suggestion about "Salut à Toi" but that's too new to be what I was thinking about).
@mmn I guess you don't mean movim.eu but mentioning it just in case.

@mmn What did they use pubsub for?
